Which is controlled by Trichoderma?

Trichoderma species can antagonize and control a wide range of economically important plant-pathogenic fungi and have been known as biocontrol agents against soil-borne, foliar and postharvest phytopathogenic fungal pathogens and can control also viruses and bacteria (Sivan and Chet 1992; Herrera-Estrella and Chet 1998 …

Which disease is controlled by Trichoderma Viridae?

It has been shown to provide protection against such pathogens as Rhizoctonia, Pythium and even Armillaria. It is found naturally in soil and is effective as a seed dressing in the control of seed and soil-borne diseases including Rhizoctonia solani, Macrophomina phaseolina and Fusarium species.

What is Trichoderma harzianum used for?

Trichoderma harzianum is a fungus that is also used as a fungicide. It is used for foliar application, seed treatment and soil treatment for suppression of various disease causing fungal pathogens. Commercial biotechnological products such as 3Tac have been useful for treatment of Botrytis, Fusarium and Penicillium sp.

Is Trichoderma a biological control agent?

Trichoderma spp. are free-living and abundantly present in the soil and rhizosphere region and are mycoparasitic of several soilborne plant pathogens. It has also been exploited successfully as a biocontrol agent for controlling the foliar diseases of economically important plants.

How is Trichoderma being used applied as biocontrol agent?

Trichoderma can be an important component in IPM strategies. Biocontrol mechanisms of various species of Trichoderma have been isolated and studied. They restrict the growth and proliferation of the pathogens by parasitism and antibiosis as well as molecular approaches are being done.

Can Trichoderma control nematodes?

The genus Trichoderma, mycorrhizal and endophytic fungi are the main groups of filamentous fungi studied and used as biological control agents (BCAs) against nematodes as resistance inducers.

Is Trichoderma viride a fungicide?

Bio Vaccine is a fungicide which contains Trichoderma viride and provide protection to the plant against rot and wilt diseases. It destroys fungal pathogens like Fusarium spp., Pythium, and Rhizoctonia which causes various rot and wilt diseases.

What does Trichoderma do for plants?

Trichoderma spp. significantly suppress the growth of plant pathogenic microorganisms and regulate the rate of plant growth. Recent works have shown that common plant disease such as root rot disease, damping off, wilt, fruit rot and other plant diseases can be controlled by Trichoderma spp.

What is the importance of Trichoderma?

Trichoderma species promotes the growth of plants and limits the growth of plant pathogens. Trichoderma species are effective biofungicides, enzymatically degrading other fungi, producing anti-microbial compounds that kill pathogenic fungi, and outcompeting pathogenic fungi for space and nutrients.

Why baculoviruses are excellent biological control agents?

Most of the Baculoviruses are the genus of Nucleopolyhedrovirus, which are used as biological control agents. They are pathogenic, attacking insects and such arthropods. Further, they do not impart any negative effect on mammals, birds, plants, fish or even non-target insects.

¿Cuáles son las especies de Trichoderma?

El género Trichoderma spp., fue descrito inicialmente por Persoon (1794), para clasificar cuatro especies no relacionadas entre sí en la actualidad. Entre ellas: Trichoderma viride, Xylohipha nigresce, Sporotrichum aureum, y Trichotecium roseum.

¿Cuál es el efecto de Trichoderma en la fertilización?

Trichoderma sobrevivió en el sustrato estudiado durante todo el ciclo del cultivo en niveles aproximados de 1,7 x 106 UFC/gr. de sustrato. No se pudo comprobar efecto inmovilizador de nutrientes en ningún tratamiento de fertilización.

¿Cuáles son los antibióticos de Trichoderma?

En investigaciones posteriores Webster y Lomas, citados por Díaz (2010) determinaron que Trichoderma spp. produce dos antibióticos más: gliotoxina y viridina, (Olivera Costa y Rodríguez, 2014).

¿Cuáles son los mecanismos de acción de los hongos Trichoderma?

Mecanismos de acción El efecto controlador de los hongos Trichoderma se verifica por diversos mecanismos de acción sobre el desarrollo de los hongos fitopatógenos. Entre los principales mecanismos que ejercen una acción directa está la competencia por espacio y nutrientes, el micoparasitismo y la antibiosis.
